By using CFD simulation tool FLUENT we simulate the battery transient heat transfer process and get a set of temperature profiles at the center of the battery under different discharge rates(0.5C, 1.0C, 1.5C and 2.0C) and heat dissipation conditions(h = 0W/m2∙K, 5W/m2∙K, 15W/m2∙K, 40W/m2∙K).
To adjust the internal heating rate according to the 3D fitting curves above, the user-defined function (UDF) built in CFD simulation tool FLUENT is used.
Using FLUENT software, the author comparing the results, the data obtained from the lumped parameter method coincides well with the data from simulation.
